How to overlay properties on a chart

Charts can be overlaid by properties (i.e., columns). The overlay properties are displayed on the lower left corner of the chart. With the overlay properties, you can easily peek at what the currently selected sample is all about, e.g., the label and predicted label, etc.

To overlay properties, open the Tweak Chart dialog by clicking the wrench icon in the Charts’ toolbar. The far right column is Show tweak overlay, where you can select the properties (columns) you want to overlay on the chart.

An alternative way to overlay properties on an existing chart is to drag and drop the column into the chart as shown in the screenshot below. You can also reorder the existing overlay properties by dragging and dropping.

There is a simpler way to overlay properties on an image chart. You can simply select the image column and the columns you want to overlay on the chart before creating the chart.

The overlay properties can be edited in place, which is equivalent to editing them in the Rows panel.
